Be it known that I,Lrii.ii\nV G.' Karr-is, a citizen ofthe United States,.a'nd a resident of National llVIilitaryHome, in the county vof Leavenworth and State of; Kansas, have invented anew Vand Improved Double-Door Bolt, of which the followingis a full, clear, and exact description.

This invention" relates to locking' devicesl for double doors, ,double` hinge ywindow` sashes and the like, employed in homes, pub# lic buildings, schools, garages, barns, etc., where onev section of the door or window is used for' ordinary ingress andy egress, 'but where both doors or sashes may be instantly opened'when` desiredf- The vinvention has for itsvgeneralobjects' to provide animproved operating means for the head and foot boltsof'the 'locking device, so as to be reliable and eliicient in use, comparatively inexpensive to construct, of

durable and substantialdesign, and capable l of being readily adjusted to place the operating handle or lever in the best position.

A more Aspecific object of the invention'fis the provision of bolt-operating means which is so designed as to insure positive,v 'easy `Sipecification of Letters Patent.; Application led May v15, 1917'.V y-Seria1Nor- 168,626'. z

and smooth movement of tliebolts, ai'1cl-in-` cluding means whereby the operating handle can be ladjustably connected lto the bolts in a simple, secure and eiiicient manner.

With such objects inv View, and' others which will appear as the description proceeds, the invention comprises variousnovel ofy parts which will be set forth with par! ticularity in the following description and claims appended hereto.4

' fReferring to the drawings, -1 and 2 desig-A nate separate doorswhich swing` on yhinges 3l and one beingheld in closed position by headand foot bolts 4 and 5 which engage. respectively infsockets '16 and 7;. Y

"Ihe bolts are adapted to be moved to'and from lockingv position :by an operating def` `vice A. which comprises a-handle or lever 8 which is adjustably connectedwith a disk 9"' which, together with the1handle,fis fas-v tenedvbyfa pivot bolt 1 0'which' screws into and on the disk 9 are pins 12 disposed .at diametrically oppositel points `by which the bolts 4 and 5.are pivotally connected with the disk. The pivoted ends of the-bolts lieV under the disk or between the samel and the base plate, .which latter has a central boss 13 to -form a spacer between Vthe-base plate and the disk'to accommodate the bolts. The

vkbase plate has arcuate recesses 14 concentric with thel central pivot 10, and the pins 12 have a sliding engagement in the recesses the base plate 11 fastened to vthe door 2,

to limit vthe movement vof the bolts in the Y operationv of the locking device. The disk 9 is fastened to the-handle Sl byl a screw 15, the head ofwhich .is countersunk in the disk, as clearly shownin Fig.v 6, saiddisk being provided with a plurality of aperturesl 1G, whereby the screw can bevplaced inv any aperture to adjustably connect' the handle ywith the disk. 'Io insure positive action between the handle and disk the `latter on its front face has a plurality of spacedpro-v jections 17 anyone of which is engageable in a depression 18 in the under side ofthe handle 8, as Vclearly shown in Fig. 6. By`

this means the handle can be adjusted to the disk and thereby adjustably relatedto vthe bolts so as to place the handle'in any de` sired position. l I

.From the foregoing description taken in connection with the accompanying drawing, Y the advantages of the construction and method of operation will be readily underthe invention appertains,and whilev I have stood by those skilled inthe artto whichV l described the .principle of operation, to-rv gether with the device which I now consider to be-the best ernbodiiirent thereof, I desire base plate having a raised-portionand arcuate slots, a stud projecting from the raised portion, a disk on the stud andA extending outwardly beyond the raised portion, whereby. a recess is provided between the diskand plate, bolts extending into the recess and located at opposite sides of the raised portion, means forming pivots vbetween the diskand bolts and also forming members engaged in the slots of the base plate to limit the turning movement of the disk, and means connected withthe disk forturning the same.

2. Thecombination of a plurality of bolts, with operatingV means therefor comprising a ybase plate, a central pivot stud thereon,

on the disk and to which the bolts are pivyotally connected,-said pins extending` into the arcuate slots, a handle on the stud, and

means for adjustably fastening the handle to the disk.

3. The combination of a plurality ofbolts, with operating means therefor comprising a base plate, a central pivot stud thereon, said base plate having arcuate slots concen tric with the stud, a disk on the stud, pins' on the disk and to which the bolts are pivotally connected, said pins extending into the arcuate slots, a handle on the stud, means for vadjustably fastening the handle yto vthe disk, interengaging means between the handie and disk, whereby the handleV AcanE be adjusted to different angular positions, and fastening means securing the `disk and handle together and holding the lsame interlocked.
